IMHO tags only act as fashion statements for our luggage!
With one exception, I seem to gain very little benefit if not any, from priority, business or even first class tags - especially with QF!
The one exception is HK airport- it appears that the HK handlers actually take time to read tags and action them accordingly!
On my last trip to NA, the time saved going through immigration with the APEC card was quickly deemed useless by having to wait until the end for my luggage to arrive - both ways!!! So the bright yellow QF 1st class tag and the OWE purple & green tag stood for jack!
So should Chooms had have requested the tag? Hell yeah! Would have it made any difference? Hell No!
Out of interest I have always wanted to know someone that has experienced their luggage being the first to come out? Anyone here?
If this miracle actually happened to me I dont think I could resist the temptation to strut like a rooster around the carousel a few times with bags in hand!!!

er well maybe nawt!
